The Department of Education issued a resource guide on Tuesday that guides teachers on how they should treat undocumented students, and encourages them to boost educational and career opportunities for those students.

“Teachers … who serve immigrant students should understand the cultural and educational backgrounds of their students,” the 63-page document recommended. “The development of trusting relationships with educators is especially important for undocumented youth, and affirming attitudes toward students’ backgrounds and cultures may help to facilitate greater mutual trust.”
